Lafarge SFTM blended cement is a portland-silica fume cement produced by inter-grinding portland cement clinker, silica fume, and gypsum. Lafarge SF Cement is recommended for structures exposed to seawater, chloride ions, and deicing salts, as well as for concrete pipes, water treatment plants, pulp and paper mills, and concrete structures exposed to mild chemical attack. Lafarge SF Cement can be used to produce concrete with a significantly higher compressive strength than normal concrete.
Lafarge SFTM can produce concrete that has:
- superior strength
- increased resistance to alkali aggregate reaction
- increased resistance to sulfate attack
- reduced permeability
- good freeze-thaw resistance
- good salt scaling resistance
As with all concrete, for good freeze-thaw resistance and good deicer scaling resistance, a properly designed mixture that is finished and cured in accordance with ACI and CSA specifications and standards is essential. Lafarge blended cements provides a significant contribution to sustainable construction. Their use in concrete production consumes less energy and offers improved efficiency and building performance. Blended cements can contribute to the achievement of LEED (Leadership in Energy and Environmental Design) points.
